A-side B-side is an artist run gallery, project space and studios. The gallery is part of the Hackney Downs studios complex - a massive site incorporating 70 purpose built studios, 9 venues and 4 rooftops.
It's a really exciting place with all kinds of events happening; markets, gigs, exhibitions, film shoots and much, much more. Streetfeast is currently here every Friday too - yum!
Some really nice pics of the complex here
